6.5.3 Port 2 Setup
Register
Content
Description
10,040
Enable
This parameter defines if this Modbus Port will be
used. If the parameter is set to 0, the port is
disabled. A value of 1 enables the port.
10,041
Type
This parameter specifies if the port will emulate a
Modbus Master device (0), a Modbus Slave device
without pass-through (1), a Modbus Slave device
with unformatted pass-through (2), a Modbus Slave
device with formatted pass-through and data
swapping (3), or a Modbus Slave device with
formatted pass-through and no data swapping (4).
10,042
Float Flag
This flag specifies if the floating-point data access
functionality is to be implemented. If the float flag is
set to 1, Modbus functions 3, 6, and 16 will
interpret floating-point values for registers as
specified by the two following parameters.
10,043
Float Start
This parameter defines the first register of floating-
point data. All requests with register values greater
than or equal to this value will be considered
floating-point data requests. This parameter is only
used if the Float Flag is enabled.
10,044
Float Offset
This parameter defines the start register for
floating-point data in the internal database. This
parameter is only used if the Float Flag is enabled.
10,045
Protocol
This parameter specifies the Modbus protocol to be
used on the port. Valid protocols are: 0 = Modbus
RTU and 1 = Modbus ASCII.
10,046
Baud Rate
This is the baud rate to be used on the port. Enter
the baud rate as a value. For example, to select
19K baud, enter 19200. Valid entries are 110, 150,
300, 600, 1200, 2400, 4800, 9600, 19200, 28800,
384 (for 38400 bps), 576 (for 57600 bps), and 115
(for 115,200 bps).
10,047
Parity
This is the parity code to be used for the port.
Values are None, Odd, Even.
10,048
Data Bits
This parameter sets the number of data bits for
each word used by the protocol. Valid entries for
this field are 5 through 8.
10,049
Stop Bits
This parameter sets the number of stop bits for
each data value sent. Valid entries are 1 and 2.
10,050
RTS On
This parameter sets the number of milliseconds to
delay after RTS is asserted before the data will be
transmitted. Valid values are in the range of 0 to
65535 milliseconds.
10,051
RTS Off
This parameter sets the number of milliseconds to
delay after the last byte of data is sent before the
RTS modem signal will be set low. Valid values are
in the range of 0 to 65535.
